An electrical heating coil is immersed in 3.52kg of water at 22C. The coil, which has a resistance of 230 ohms warms the water to 32C in 3.5 min. At what potential difference does the coil operate?
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.
