A 120 V house circuit fused for 25 A has operating on it the following: two 75 W bulbs, a 1500 W heater, a 20 W radio, a1.5 W clock. (a) How large a current is required? (b)Will the fuse blow if a second electric heater rated at 1500 W is plugged into it?
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.
