The number of heaters that can safely be operated in the circuit is 5 heaters.
From the question given above, the following data were obtained:
Power of heater = 300 W
Voltage (V) = 110 V
Current (I) = 15 A
Voltage (V) = 110 V
Current (I) = 15 A
P = IV
P = 15 × 110
Thus, the power that can be drawn from the circuit is 1650 W
Power of heater = 300 W
Power of Circuit = 1650 W
[tex]Number \: of \: heaters \: = \frac{power \: of \: circuit}{power \: of \: heater} \\ \\ = \frac{1650}{300} \\ \\ = 5.5[/tex]
From the calculation made above, the number of heaters that can be operated safely in the circuit is 5 heaters.
