Electricity II Quiz

If a potential difference of 6V is applied to a 3-kΩ resistance, calculate the current that will flow through it.

If a current of 6A flows through a resistance of 80Ω, calculate the potential difference across it.

What is the total voltage, resistance and current in a series circuit?

If you have a parallel circuit like this, what is the total resistance and voltage? And voltage and current on A, B, and C?

10 amps flow through a 2-ohm resistor. Calculate the power that is generated in the resistor.

Calculate the power involved when an x-ray exposure of 50kV and 5mAs is made. Assume that the exposure time involved is 20ms.
