More information is needed.
Draw a circuit with a battery connected to four resistors, R1, R2, R3, and R4, as follows. Resistors R1 and R2 are connected in parallel with each other, resistors R3 and R4 are connected in parallel with each other, and both parallel sets of resistors are connected in series with each other across the battery.
How to you calculate the total resistance in a series circuit?
R1 + R2+ R3
R1 - R2 - R3
1/R1 + 1/R2 + 1/R3
R1 = R2 = R3
How do you calculate total resistance in a parallel circuit?
R1 + R2 + R3
R1 - R2 - R3
1/R1 +1/R2 + 1/R3 = 1/RT
R1 = R2 = R3
What is the equivalent or total resistance (Re) across this circuit?
