Question

calculate power ? if V= 100 and r is 20ohm​

Answer 1

✠ Given Question :

• calculate power ? if V= 100 and r is 2ohm

✠ Required Solution :

★ Values Given to us :

• ➸ Resistance is 20 Ohm

• ➸ Volt is 100 volt

★ Formula Used Here :

• ➸ P = V² / R

★ Where :

• ➸ P = Power

• ➸ V = potential difference

• ➸ R = Resistance

✠ Putting Values in Formula :

• ➸ P = (100)² / 20

• ➸ P = 10000 / 20

• ➸ P = 500 Watt

⠀⠀⠀⠀★ Power is 500 Watt ★

Answer 2

Calculating power in terms of voltage and resistance i.e,

P= V^2/R
P= 100*100/20
P= 10000/20
P= 500W
