Answer:
80Ω
Explanation:
Resistance in a series circuit (when one resistor is after another in the same line) is calculated with the following equation
Total resistance = R1 + R2 + R3...Rn
Substitute in your values and solve for total resistance
Total resistance = 60 + 20 = 80Ω
Answer:
electricity
If a rod is charged it is because of the electrical force acting on it
