Electric Field

A current of 0.2A flows through a resistor of 10 ohms. Calculate the p.d. across the resistor.

A p.d. of 12V is appled across a lamp of 24 Ohms and the lamp lights up. Calculate the current passing through the lamp.

A large battery is labelled with various items of information about the battery.

One of these items of information in the option below is the electromotive force (e.m.f.) of the battery.

What is the e.m.f. of the battery?

The circuit shown is being used to measure the resistance of resistor Z.

What is the correct combination of meters to determine the resistance of resistor Z?

The potential difference across an appliance in a circuit is 220V. If the resistance posed by the appliance to the flow of current is 18.3 Ohms, calculate the current flowing through the appliance.
