Question

for a series circuit, the current through the circuit is the ________ (same/different). The voltage at each resistor is _______ (same/different). What is the equation used to calculate these?

Answer 1

For a series circuit, the current through the circuit is the same, while the voltage at each resistor is different. The equation used to calculate the current in a series circuit is I = V_total / R_total, where I is the current, V_total is the total voltage in the circuit, and R_total is the total resistance of the circuit, which is the sum of the resistance of each component. The voltage across each resistor in a series circuit can be calculated using Ohm's law: V = I * R, where V is the voltage, I is the current, and R is the resistance of the resistor.
