What is the formula for resistance?
Current x voltage
Voltage x resistivity
This symbol signifies which of the following device?
Which of the following can be used to measure resistance?
Voltmeter & ammeter
Calculate the resistance of a metal wire when a voltage of 8 V across it causes a current of 2 A to flow through it.
What formula do you use for calculating resistors in parallel?
R = R₁ + R₂
1/R = 1/R₁ + 1/R₂
V = V₁ + V₂
R₁/R₂ = R₃/R₄
What is the function of a resistor?
Convert electrical potential energy to some other form of energy
Split the voltage of a circuit
