3. A sensor uses 2x104 A of current when it is operated by a 3V battery. What is the resistance of the sensor circuit? 15,00052 4. If the voltage across a circuit is kept constant and the resistance is doubled, what effect does this have on the circuit's current? 5. What is the effect on the current in a circuit if both the voltage and the resistance are doubled? 6. Two wires can be placed across the terminals of a 6V battery. One has a high resistance, and the other has a low resistance. Which wire will produce thermal energy at a faster rate? Why? 7. A voltage source is able to send 5x 1016 electrons (charge of one electron is 1.6x10"C) through a 100 resistor every 2 milliseconds. What is the voltage of the source? 40V 8. A 120V source is applied over a 50$2 resistor. How many electrons would flow through the resistor every minute? 9x1020e's d Power
