Two heaters A and B are in parallel across supply voltage V. Heater A produces 757 kcal in 20 min and B produces 1252 kcal in 10 min. The resistance of A is 10 ohm. What is the resistance of B in kiloohms? If the same heaters are connected in series across the voltage V, how much heat would be produced in calories in 5 minutes?
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.
