Content 2.00 A 2.00 A In a parallel circuit, the voltage drops across each resistor should equal the voltage of the battery. Using the voltmeter you will demonstrate that this is true for the circuit you've created. Record your results in the table below: R, Voltage R2 Voltage Battery Voltage 6.0 6.0 6.0 The current through each resistor is affected by the branching in the parallel circuit. In the table below, record the current coming out of the battery, the current going into each resistor and the current flowing back to the battery. Current Out Current to Current to R2 Current Into of Battery R1 Battery 2.0 amps 1.0amps 1.0amps 2.0amps Since the voltage across each resistor in a parallel circuit is the same, we approach finding the equivalent resistance from the sum of the currents. This gives the following relationship for calculating the equivalent resistance in a parallel circuit. 1 1 1 + Reg R1 R2 Using the relationship for resistors in parallel, find the equivalent resistance in the circuit you've assembled and record in the table below: Resistor 1 Resistor 2 Equivalent Resistance 6.0 6.0 12.0 Apply Ohm's Law to your circuit to calculate the current to demonstrate that the ammeter reading is correct (recall that now R is the equivalent resistance in the circuit). 19 Current = 1 = V 0. 5amps = 12R Result of this calculation = 2 mA A
