The voltage is presented by the equation V = IR where V
is voltage in V, I is current in amperes ad R is resistance in ohms. A circuit
has a voltage of 20V supplied from a power supply and an ammeter in the circuit
gives a reading of 0.1A. The resistance can be solved through V= IR, 20 V = R
(0.1A) and the resistance is 200 Ω.
