Question
What types of load are there (resistive loads, inductive loads, lamp and capacitor loads)?
Answer
The load types and their characteristics are as follows.
1. Resistive Loads
Nichrome heaters and other loads to which the same current continues to flow when voltage is applied
2. Inductive Loads
Motors, solenoids, and other loads with inrush current
3. Lamp and Capacitor Loads
Loads with inrush current even larger than with inductive loads
AC Loads and Inrush Current:
| Type of load | Ratio of inrush current to steady-state current | Waveform | |
| Solenoid |  | Approx. 10 |  |
| Incandescent bulb |  | Approx. 10 to 15 | |
| Motor |  | Approx. 5 to 10 | |
| Relay |  | Approx. 2 to 3 | |
| Capacitor |  | Approx. 20 to 50 | |
| Resistive load |  | 1 | |
DC Loads and Inrush Current:

Other General Purpose Relays FAQ
-
The Relay does not operate even when voltage is applied. Why is this?
-
We were using G2R General Purpose Relay to turn a solenoid valve ON and OFF, and sparks at the contact damaged the relay after only about 3 months of use. What caused this, and what kind of countermeasure is there for it?
-
A Relay burned out. Why is this?
