Question

calculate power ? if V= 10 and r is 20ohm​

Answer 1

✠ Given Question :

• calculate power ? if V= 10 and r is 2ohm

✠ Required Solution :

★ Values Given to us :

• ➸ Resistance is 20 Ohm

• ➸ Volt is 10 volt

★ Formula Used Here :

• ➸ P = V² / R

★ Where :

• ➸ P = Power

• ➸ V = potential difference

• ➸ R = Resistance

✠ Putting Values in Formula :

• ➸ P = (10)² / 20

• ➸ P = 100 / 20

• ➸ P = 5Watt

⠀⠀⠀⠀★ Power is 5 Watt ★

Answer 2

Answer:

Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).
