A device operates for 8 consecutive days without ever turning off. It uses about 2A when connected to a voltage source. If the device's total cost operation is $2.60 and the electrical energy is at (5.2 cents/kWh), what is is the voltage source that the device is connected to ? 180V 288V 14V 144V none
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.
