3. Calculate the power rating of a home appliance (in kilowatts) that uses 8 amps of current when plugged into a 120-volt outlet. 4. Calculate the power of a motor that draws a current of 2 A when connected to a 12 volt battery. 5. Your alarm clock is connected to a 120 volt circuit and draws 0.5 A of current. a.
Most flashlights use multiple 1.5 volt batteries to power a light bulb with a voltage rating of several volts. Draw a schematic diagram of showing how multiple batteries may be connected to achieve a total voltage greater than any one of the batteries’ individual voltages.
What does the amp-hour capacity of a chemical battery represent? What does it mean if a battery is rated at, say, 150 amp-hours?
Draw a schematic diagram of showing how multiple batteries may be connected to achieve a total voltage greater than any one of the batteries' individual voltages. Reveal Answer Follow-up question: if each of these batteries outputs a voltage of 1.5 volts, how much voltage does the light bulb experience?
How much current flows through a 16 V battery that has a resistance of 5.1 Ω? 5. The human body offers a very small amount of resistance (let’s say 1 mΩ for argument).
A circuit containing two 6 V batteries has a total voltage of 12 V. [Note: The batteries must be connected positive to negative for the voltages to add.] current in the circuit? The resistance (R) is 12 ohms. The voltage (V) is 120 volts. The current in the toaster circuit is 10 amps. The amount of current (I) in the circuit.
Suppose a battery outputs a voltage of 9 volts. Using algebra, calculate how many joules of energy are imparted to every individual electron moving through this battery. What is the difference between DC and AC electricity? Take the Voltage, Current, and Resistance (Basic Electricity) worksheet.
