Explanation: The relation between current, voltage and resistance can be expressed using Ohm's law as follows: V = I*R where: V is the volt = 100 volts I is the current we want to calculate R is the resistance = 5 Ohm
Substitute with the givens in the above relation to get the current as follows: V = I*R I = v/r I = 100/5 I = 20 amperes
