if vs = 10 v in the circuit above, what are the following voltages? course hero

Why are current and voltage not in series with each other?

And let's apply Ohm's law here. So we know V is 50. V is 50. That's equal to I times R, R is 10. R is 10, so I is 50 divided by 10, that's going to be five amperes. So I is five. So the current in this circuit is going to be five, this is positive, this is negative, so the current flows from positive down to the negative terminal.

What happens to current and voltage in a circuit when current changes?

Physics questions and answers. Question 1: Verify that the Kirchhoff's loop rule for the loop defined by points 1, 2 and 3 is valid, i.e. Ɛ – V1 – V2 = 0 Question 2: Based on the values measured for the voltages V1, V2, V3 and the numerical values you have for the resistance values R1, R2, R3 calculate the current through each resistor ...

What is the voltage across the resistor in this circuit?

If the voltage across the capacitor is 10 V, voltage will be across the resistor right after the circuit is connected? V R = __ 10V __ The loop rule for circuits may be useful here. The total change in voltage (or the total potential difference) must be zero whenever we go around a closed loop.

What is voltage division rule?

Voltage Divider Rule. The voltage division rule states that: The voltage divided between two series resistors, are in direct proportion to their resistance. Which means your circuit can have more than 2 resistors! Voltage Divider Rule Formula: Example of Voltage Divider Rule Equation:

What is a potentiometer?

A potentiometer is passive electronic component with a sliding or rotating function that acts as an adjustable voltage divider. The voltage input is applied across the entire length of the Potentiometer and output voltage (voltage drop) is controlled with the fixed and sliding contact of the potentiometer.

Why is a potentiometer useful?

The potentiometer is useful to help achieve a variable voltage from a fixed-voltage source. It can connect the outer terminals of a potentiometer across the voltage source and control the voltage you need between your potentiometer and one of the outer terminals for your circuit.

How does a manual wiper work?

How does it work?#N#The manual wiper which is movable, touches a resistive strip of material. When it is moved up closer to terminal 1 and away from terminal 2, resistance is lowered to terminal 1 while resistance is raised at terminal 2 and vice versa.
