Measured value of the resistor rated at 39Ω R3 = _____ 2. Carefully rewrite Equations 23-1, 23-2 and 23-3 with the appropriate measured (not rated) values for emf and resistances substituted into them. Use 100Ω for the value of R2 in your calculation. You will be setting a variable resistor to that value soon.

When the resistors are connected in parallel, each resistor experiences the same voltage drop. Hence the full voltage of the voltage source V is applied to each resistor, soV = V. 1 = V 2 = V 3 Thus IR 1 = IR 2 = IR 3 and 1 R eq = 1 R 1 + 1 R 2 + 1 R 3 Extending this result to the case of several resistances of some number n, the equivalent resistance is

The calculated equivalent resistances for the series circuits will abide by the equation Req = R1 + R2 and for the parallel circuits the value will be similar to 1/Req = 1/R1 + 1/R2. The current flow is expected to be uniform throughout the series circuits, but will be stronger through the smaller resistor in the parallel …

Parallel circuits are composed of resistors that are connected parallel to each other as rungs on a ladder are parallel to each other. The effective resistance is reduced below the smallest resistor since each resistor offers another path for the electrons to pass through. The effective resistance is given by the following equation.

Parallel Circuits. The sum of the currents flowing thru each resistor in parallel must equal the total current flowing in the circuit. The voltage drops across each resistor in parallel is the same as the total voltage being supplied to the circuit. To find the total resistance, RT, of a parallel circuit, use the following equation:
