A single 12 Volt battery is connected to a single 40 Ohm resistor. a. how much current is flowing through the resistor ? b. what power is being consumed by the resistor ?

A toaster, a speaker, and a lamp are each plugged in parallel into a 110 V outlet with a 20 A fuse. a.) If the toaster draws 1500 Watts of power, the speaker draws 900 Watts of power, and the lamp draws 60 Watts of power, what current is drawn by each device? b.) Will this combination blow the fuse? Why or why not?

A capacitor is connected in series with a resistor and a switch. With the switch open, the capacitor is charged to 9.0 V. When the switch is closed, how long will it take for the voltage across the capacitor to drop to 6.0 V if the time constant of the circuit is 4.0 s?   a. 0.3 s b. 1.2 s c. 1.6 s d. 2.7 s

A physics student has a single-occupancy dorm room. The student has a small refrigerator that runs with a current 4 A, a lamp that contains a 100-W bulb, an overhead light with a 60-W bulb, and various other small devices adding up to 8 w. All the appliances run on a voltage of 110 V. Overall Hint a. What is the total power used by the dorm room (while the refrigerator runs)? Total power used by the dorm room is W. b. Assuming that the power plant for the electricity is 10 km away and uses 00-gauge copper wire (diameter 9.266 mm), how much power is dissipated in transmission (remember to count the return wire), if the power plant is directly providing the 110-V? (To be more precise, the power plant is providing the voltage it needs to provide, so that the voltage at the dorm room is 110 V.) Hint for part (b) Power of W is dissipated in transmission at 110 V. c. The most common way to increase the efficiency of power transmission is by using higher voltage for long-distance transmission…
