The current in a toaster is 20 amps, and its voltage is 200 volts. What is the resistance in the toaster?
Ohm's law deals with the relation between
voltage and current in an ideal conductor. It states that: Potential difference
across a conductor is proportional to the current that pass through it. It is
expressed as V=IR.
V = IR
200 = 20R
R = 10 ohms
