Four resistors in series 5ohms, 10ohms, 5ohms, 20ohms
Total resistance is -
5 ohms
30 ohms
40 ohms
50 ohms
Resistors in series 5ohms, 5ohms, 5ohms
What is the total resistance
15ohms
20ohms
5ohms
30ohms
Resistors in parallel - 5ohms, 5ohms, 5ohms
which is the correct formula?
Rt = 1/R1 + 1/R2 + 1/R3
1/Rt = 1/R1 + 1/R2 + 1/R3
Rt = 1/R1 x 1/R2 x 1/R3
1/Rt = R1 + R2 + R3
Resistors in parallel, 5ohms, 5ohms, 5ohms
total resistance is
5 + 5 + 5 = 15 ohms
1/5 + 1/5 + 1/5 = 3/5 ohms
1/5 + 1/5 + 1/5 = 3/5 flipped = 5/3 ohms
1/5 + 1/5 + 1/5 = 3/15 ohms
