find resistor in circuit Quiz Practice Quiz…

60 ohms — In series, resistors add directly: RT = R1 + R2 + R3.

1/RT = 1/R1 + 1/R2 + 1/R3 — The reciprocal of RT equals the sum of the reciprocals of individual resistances.

50 ohms — For equal parallel resistors: RT = R/n. Here, n=2 (two resistors)

Ohm (?) — Resistance is measured in Ohms, often represented by the Greek letter omega (?).

The same — Current remains constant throughout a series circuit.

Question 1 of 5

In a series circuit, what is the total resistance (RT) if R1 = 10 ohms, R2 = 20 ohms, and R3 = 30 ohms?

In series, resistors add directly: RT = R1 + R2 + R3.

Question 2 of 5

The reciprocal of RT equals the sum of the reciprocals of individual resistances.
