Apply 12 volts directly to the horn an if it blows it is good. If not it is bad. Check the fuse for the horn. Check the horn relay. Check the horn button in the steering wheel. Check all wiring and the ground connection.
observations
It is in parallel, so one light can be on while others are turned off.
negative
A. It is measured in volts. B. It is related to current and resistance by Ohm's Law. D. It's what makes current flow in a circuit.
A it is an EMF it can exists in its form without performing any work
electromagnetic
In a series circuit the current is the same at every point. This is Kirchoff's current law.
No. Touching a live electric current is never a good idea.
A 120V power supply connected to a 30 Ohm resistor will produce 120/30 or 4 amps of current.
a copper wire carrying current and another magnet.
Because it is. Gravitational potential energy is energy stored in the gravitational field, electrical potential energy is energy stored in the electric field, magnetic potential energy is stored in the magnetic field, etc.
Do not use any equipment that plugs into a wall outlet
