Question

Use the formula P = V2 to calculate the value of P when V = 6 x 106 and R = 7.2 x108

Answer 1

P = 5.0 x 10⁴ Watts

Explanation:

The formula to calculate the Electrical Power(P) from Voltage(V) and Resistance(R) is:

`P=(V^(2))/(R)`

Given values are:

`V=6 * 10^(6)` Volts

`R=7.2 * 10^(8)` Ohm

Substituting these values in the above formula gives us:

`P=((6 * 10^(6))^(2))/(7.2 * 10^(8))\\\\ P=(36 * 10^(12))/(7.2 * 10^8)}\\\\ P=5.0 * 10^(4)`

Thus, the value of power will be 5.0 x 10⁴ Watts
