Determine the operating time of the electric stove if it has released 48600J of heat at a current in the circuit of 9A, the resistance of the spiral is 12Ohm.
These tasks: Q (heat released during the operation of the electric stove) = 48600 J; I (current in the circuit) = 9 A; R (spiral resistance of the tile used) = 12 ohms.
The operating time of the used electric stove is expressed from the formula: Q = I2 * R * t, whence t = Q / (I ^ 2 * R).
Let’s make a calculation: t = 48600 / (9 ^ 2 * 12) = 50 s.
Answer: The electric stove used worked for 50 seconds.
