The current in a radio measures 12 amps. the resistance of the radio is 4 ohms. what is the voltage? question 1 options: 3 v 48 v 3 a 48 ohms

As per ohm's law we can say that voltage across the ends of a resistor is always product of the resistance with current flows through it.

So we can write

given that

i = 12 A

R = 4 ohm

now we can say from the above formula

photocells convert light energy to electricity

there are no atoms
