Electric Circuits Part 1

The voltage across two points in an electric circuit is 1 423 mV. A charge of 2 748 mC moves between these two points when a power source does work on the charge.

Determine the amount of work done by the power source.

Work done (W), potential difference (V), and charge moved (Q) are three variables used in electric circuits calculations.

Which one of the following equations correctly represents the relationship between these quantities?

1 488 electrons move past a fixed point in a circuit in 0,4 s

. What is the current at that point in the circuit?

What is the potential difference across resistor R3? Round your answer to one decimal place.
