Using a material that is ‘Ohmic’ (it follows Ohm’s Law), you make a circuit using wire, a battery, and a resistor. After measuri
ng V, I, and R across the circuit, you switch out the original resistor with one 3 times more resistive. When you measure V, I, and R again, how will the new values compare to the old?
When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and the current flowing in the cirucit decreases by a factor 3.
<h3>Ohm's law</h3>
Ohm's law states that, the current flowing in a conductor is directly proportional to the potential across the conductor.
V = IR
where;
I is the current in the circuit
V is voltage
R is the resistance
When the resistance increases, the current flowing in the circuit decreases.
When the original resistor is replaced with 3 times more resistive material, the resistance of the circuit increases by factor of 3 and the current flowing in the cirucit decreases by a factor 3.
