Ohm's Law, Power, Simple Circuits (1) A 6.0-volt battery is connected, within a simple electrical circuit, to a resistor having a resistance of 2.0 ohms (). How much current runs through the circuit? a. How many coulombs would travel through the circuit in 3 seconds? 10 seconds? (2) If you wanted the circuit in ques #1 to have a current of 6.0 A, state two separate changes you could make to the circuit. (3) A motor, with a resistance of 25 , is connected to a voltage source resulting in a current of 6.5 A. What is the voltage of the source? (4) A transistor radio uses 2.0 x 10-4 A of current when operated off of a 3.0-volt battery. What is the resistance of the circuit? (5) If a lamp draws a current of 0.5 A when connected to a 120-volt source, a. What is the resistance of the lamp? b. What is the power consumption of the lamp? (6) Using the circuit shown below: a. If V1 = 45-volts and R1 = 5 , calculate the current through the circuit (A1). b. What is the power consumed by the circuit? c. How much energy is used by the circuit in 5 minutes? (7) Draw a simple circuit that shows a 60-volt battery, a resistor (of 15-), and an ammeter. What is the reading of the ammeter? (8) Draw a simple circuit that shows a battery, an ammeter that reads 2.5 A, a resistor of 16-, and a voltmeter across the resistor. a. What is the reading of the voltmeter? b. What is the power consumption of this circuit? c. How much energy is used by this circuit in 1 minute?
