An immersion heater has a resistance of 5.0 ohms while drawing a current of 3.0 amperes. how much electrical energy is delivered to the heater during 200. seconds of operation? 1. 3.0 × 103 j 2. 6.0 × 103 j 3. 9.0 × 103 j 4. 1.5 × 104 j

Respuesta :

The power of the heater can be calculated by multiplying current, voltage of a circuit and the time. For this problem, we first calculate the voltage of the circuit then multiply this to the current.

P = IVt

V = IR = 3(5) = 15

P = 3(15) (200) = 9000 J

The electrical heat energy delivered by the heater is 9000 J

What is energy delivered by an immersion heater?

The electrical heat energy producesd by an immersion heater is calculated using the formula below:

  • Energy = I^2Rt

where

  • I is current
  • R is resistance
  • t is time

Energy = 3^2 × 5 × 200

Energy = 9000 J

Therefore, the electrical heat energy delivered by the heater is 9000 J
