... Ohm’s Law states that the current flowing in a conductor varies directly with the voltage drop across the conductor. Hence, the current-voltage (I-V) graph is a straight line (see below), but, as we’ll see later, only for constant temperature. What happens when temperature increases? This is an issu ...
