Solved Given the following circuit: R1 R2 R3 R4 R5 If R1 36 | Chegg.com

Engineering; Electrical Engineering; Electrical Engineering questions and answers; Given the following circuit: R1 R2 R3 R4 R5 If R1 36 Ω, R2-12 Ω, R3-12 Ω, R4-24 Ω, R5-12 Ω and Vs 9 Volts, determine the circuit equivalent resistance (REQ) and the circuit current (ID.

What is the voltage drop across a resistor?

The voltage drop across a resistor is nothing but the voltage value across a resistor. Sometimes it is also called ‘voltage over the resistor’ or simply ‘Voltage drop’.

Why is voltage the same across parallel resistors?

This is because both the resistors have common potential points shared between them (point A & point B), so the voltage will be the same but the current will be different.

How to determine voltage drop?

What is the voltage drop across a resistor? 1 The voltage drop across a resistor is nothing but the voltage value across a resistor. Sometimes it is also called ‘voltage over the resistor’ or simply ‘Voltage drop’. 2 It is generally indicated as:#N#‘V (drop) ‘ or ‘Vr’ or ‘Vd’#N#For multiple resistors, it is written as Vr1, Vr2, Vr3, and so on.

What is the unit of resistance of a device?

The constant of proportionality, R, is known as the resistance of the device and is equal to the slope of the I–V characteristic. The unit of resistance is ohm, the symbol is Ω. Any device with a linear VI characteristic is called a resistor.

What is a V drop?

For multiple resistors, it is written as Vr1, Vr2, Vr3, and so on. As we all know, a resistor is a device that offers resistance to the current flowing through it.

How many resistors are connected in series?

There are N equal resistors connected in series. Each resistor has a resistance of R=30Ω. What is the total equivalent resistance Req if we have N=20 resistors?

How is a dieelectric material charged?

A dieelectric material is charged by a current. A charge of 20C is accumulated in the material after 0.5s. The charge current is:

What is the charge of a dieelectric material?

A dieelectric material is charged by a current of 7A. A charge of 21C will be accumulated in the material after

What is the charge of an electron?

The charge of an electron is given by qe = -1.602•10-19C.

Do you put a voltmeter in parallel to an element?

the voltmeter must be put in parallel to this element, while the element is still in the circuit.

Question

In the given circuit what will the voltage be across R 2 when after 25 μs the switch is moved to position 2?

Detailed Solution

Initially, the switch is in position 1. For DC supply, the inductor acts as a short circuit. The circuit becomes,

What is the total resistance of a series circuit?

The total resistance in a series circuit is equal to the sum of all the parts of that circuit, as shown in below equation.

How to find total voltage in a series circuit?

To find the total voltage across a series circuit, multiply the current by the total resistance as shown in below equation.

What is the effect of voltage drops in a series circuit?

The voltages of V1 ,V2 , and V3 in Example 2 are known as “voltage drops” or “IR drops.” Their effect is to reduce the available voltage to be applied across the other circuit components. The sum of the voltage drops in any series circuit is always equal to the applied voltage. We can verify our answer in Example 2 by using below equation

How many resistors are needed for a 120V battery?

A 120 V battery is connected in series with three resistors: 40Ω, 60Ω, and 100Ω (Figure 22). Find the voltage across each resistor.

Can Ohm's law be applied to a circuit?

Ohm’s law may now be applied to the entire series circuit or to individual component parts of the circuit. When used on individual component parts, the voltage across that part is equal to the current times the resistance of that part. For the circuit shown in Figure 20, the voltage can be determined as shown below.

How many resistors are connected in series?

There are N equal resistors connected in series. Each resistor has a resistance of R=30Ω. What is the total equivalent resistance Req if we have N=20 resistors?

How is a dieelectric material charged?
