Simple Circuit Worksheet. I ask what is the total resistance of the circuit. On the back of the page, I ask them to draw and equivalent circuit. I ask them to solve for current (I) and indicate on the schematic diagram the direction of the conventional current flow. I have them draw an “A” into the schematic diagram where you would place an ammeter to find the current of the circuit. I ask them to calculate the voltage drop across the 20 ohm resistor (V1), draw into the schematic diagram where you would place the voltmeter for V1 and what is the remaining voltage and current at B.
