1. A 10 ohm resistor is connected across a 20 V battery. What is the current that runs through the resistor? 2. Two 10 ohms resistors are connected in parallel across a 20 V battery. Determine the current through each resistor and the total current in the circuit. 3. A 20 V battery is connected to two resistors that are in series. The voltage drop across the first resistor is 3 V. What is the voltage drop across the second resistor? 4. The current through a 100 ohm resistor is 2.5 amps. What is the power dissipated in the resistor? 5. The voltage drop across a resistor is 5.0 volts and the current through it is 20 mA. What is the power dissipated through the resistor? 6. Two resistors are connected in series to a 10 V battery. If the current through the first resistor is 30 mA, what is the current through the second resistor? 7. Two resistors are connected in parallel to a 10 V battery. If the voltage drop across the first resistor is 10 V, what is the voltage drop across the second resistor? 8. Two resistors are connected in parallel to a 10 V battery. The total current through the circuit is 100 mA. If the current through the first resistor is 40 mA, what is the current through the second resistor?
