A 75 A resistor in a circuit has a current flowing through it of 2.0 A. What is

Reptile [31]

Answer:

The power dissipated by the resistor can be calculated as $P = I^{2} R$ .

Explanation:

Joules heating law states that any conductor passed with the electric current produces heating effect which is the electric power loss.

The given circuit has, $R = 75 ohm$ resistor (the unit is wrong i question because resistor's unit is ohm not Ampere).
Current flowing through the circuit is $I = 2.0 A$ .

By using joules heating theory, $P = I^{2} R$ ,

$or,$ $P = 2^{2} * 75$

$or,$ $P= 4*75$

$or$ , $P= 300 W$ .

So the power dissipated by the resistor in the circuit is 300 W.

Oksi-84 [34.3K]

Unlike charges attract .
like charges repel .

There are two types of charges

Namely :

positive
negative

On loosing electrons , a neutral body acquires positive charge .

On gaining electrons , a neutral body acquires negative charge .

The amount of charge present in a body , either positive or negative , is expressed in terms of an integral number of charge of an electron , which is considered the elementary entity of an electric charge .
