Digital Multimeter (DMM) is connected in parallel to resistor. The current coming from the voltage source flows through resistor, only in one direction. A potential drop occurs that is equal to the loss of electric potential energy as a current travels through resistor and lamp glows. Measured value by Multimeter 1k Resistor o Voltage = 5v o Resistance = 500 MΩ Example: Given Data: R = 1K V = +5 v Required Data: I = ? Formula: I = V/R Solution: I = 5/(1×10 3 ) I = 5×10 -3 I = 5 mA SIMPLE SERIES CIRCUIT WITH THREE RESISTOR OF SAME RESISTANCE Explanation The positive terminal of battery of 5V is connected to a circuit consisting of three resistors of 1kΩ through wire in series and the negative terminal of battery is connected to the ground. A lamp is connected with three resistors in a series manner. Digital Multimeter (DMM) is connected in parallel to resistors. The current coming from the voltage source flows through each resistor, so the current through each resistor is the same. For each resistor, a potential drop occurs that is equal to the loss of electric potential energy as a current travels through each resistor and the lamp glows. Measured value by Multimeter 1k Resistor o Voltage = 1.667 v o Resistance =166.667 M 1k Resistor o Voltage = 1.667 v o Resistance =166.667 M 1k Resistor o Voltage = 1.667 v o Resistance =166.667 MΩ Example: Given Data: R 1 = 1K R 2 = 1K R 3 = 1K R = (R 1 + R 2 +R 3 ) = 3k V = +5 v Required Data: I = ?  #### You've reached the end of your free preview.
