How do you high 5 scientists in jet pack joyride?

Just run into them. They automatically high five you if that is a current challenge


Working of a relay?

A relay is an electrical switch that uses an electromagnet to control the flow of electricity. When a current is applied to the electromagnet, it creates a magnetic field that pulls a switch to make or break a connection between two circuits. Relays are commonly used to control high-voltage circuits with low-voltage signals.


What can a relay be used?

A relay is an electrical switch. It allows a low current "switch" circuit to control the electricity flow of a high-current circuit load


Can Crystal Diode acts as a Automatic Switch?

A diode typically has low resistance for current in one direction, and high resistance for current in the other direction. This is not really the description of anything that could be called a 'switch'.


Is a resistor and a relay the same thing?

No, they are not the same. A resistor is a current reducer and a relay is essentially a switch (using low voltage to switch high voltage on/off)


What is the pnp switch circuit?

The PNP switch circuit uses a PNP transistor to control the flow of current based on the input signal. When the input signal is high, the transistor allows current to flow from the collector to the emitter, turning the switch "on". When the signal is low, the transistor blocks current flow, turning the switch "off".


Why don't brights work on 2002 grand am?

Check to see if the foglight switch is on. Brights (high-beams) are automatically disengaged when fog lights are being used.
