### An alarm clock draws 0.5 A of current when connected to a 120 volt circuit. Calculate its resistance.

### If a toaster produces 12 ohms of resistance in a 120-volt circuit, what is the amount of current in the circuit? (Units required)

### A walkman uses a standard 1.5 V battery. How much resistance is in the circuit if it uses a current of 0.01A?

### A circuit contains a 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current.

### An electric heater works by passing a current of 100 A though a coiled metal wire, making it red hot. If the resistance of the wire is 1.1 ohms, what voltage must be applied to it?
