Question

an electric heater draws 5A of current for 10min when connected to 230v power supply find the heat energy developed​

Answer 1

FINAL ANSWER:-

heat energy developed​ ⇒ $690000\:J$

GIVEN:-

• electric heater draws current of (I) → 5A [Ampere]

• time till electricity is conducted (t)→ 10min ⇒ 10×60sec ⇒ 600 sec

• power supply (V) → 230V [Volt]

FORMULA USED:-

$heat=volt*current*time$

$H=VIt$

TO FIND:-

the heat energy developed​

SOLUTION:-

∴ heat energy developed​ = $H=VIt$

$H=230*5*600\\H=690000\:J$
