Electric Heating of Mass
Calculator for determining temperature rise in an electric heated object or mass. Uses the principle that electric energy supplied equals thermal energy change: P·t·μ = c·m·dT. Heat loss during heating is neglected in this calculation.
Electric Heating of Mass
When an electric heater heats an object, the electric energy is transformed to heat by increased object temperature.
Formula: dT = U·I·t·μ / (c·m)
Where:
- P = power (watts, W)
- U = potential difference (volts, V)
- I = electrical current (amps, A)
- t = time (seconds)
- μ = heating efficiency (0-1)
- c = specific heat of substance (J/kg°C)
- m = mass of substance (kg)
- dT = temperature difference (°C)
Note: The mass of the heater and heat loss during heating are neglected in this calculation.
