The Formula will help you make the decision about what resistance wire/electrical heating wire specification do you need.
Temperature:
oF = (oC*1.8) + 32 | oC =(oF - 32)/1.8 | ||
Deg C | Deg F | Deg F | Deg C |
20.5 | 68.9 | 68.9 | 20.5 |
oK = oC + 273.15
oR = oF + 459.67
Ohms Law: | ||||||
V = (I)*R | V = volts, I = current in amperes, R = resistance in ohms | |||||
Volts: | 120 | 120 | 120 |
Amperes: | 0.5 | 0.5 | 0.5 |
Resistance (ohms): | 240 | 240 | 240 |
Power: | P = V*(I) | P = Power in watts, V = voltage, I = current in amperes | |
P = (I)2*R | P = Power in watts, R = resistance in ohms, I = current in amperes | ||
P = (V)2/R | P = Power in watts, V = voltage, R = resistance in ohms | ||
Voltage: | 120 | 120 | 120 |
Current, A: | 0.25 | 0.25 | 0.25 |
Resistance, ohms | 480 | 480 | 480 |
Power, watts | 30 | 30 | 30 |
