the electrical energy used by a household whose monthly electrical bill is $42, computed at the rate of $0.07 per kWh. (b) How long could this energy be used to burn ten 100 W light bulbs?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
(a) Compute the electrical energy used by a household whose monthly electrical bill is $42, computed at the rate of $0.07 per kWh.
(b) How long could this energy be used to burn ten 100 W light bulbs?
(c) If this energy were used to raise a car of mass 2230 kg, to what height would the car be raised?
