Meggar is a hand driven tool for measuring insulation resistance and earth resistance.
A superconductor truly has zero electrical resistance.It took scientists a half century to explain why, so this answer will omit the explanation of the effect.
No - attempting means trying, or sometimes intending. "I was attempting to explain how important it was, but everyone just laughed."
The biggest advantage of the Wheatstone bridge is the accuracy of the resistance readings. I had two cables short out underground, by knowing the resistance of the wires per foot I located the fault within 3 feet of where the two wires touched each other.
To answer this question you have to explain where you are measuring this voltage. Between what two points in the electrical panel. Use the discussion page for help.
the size of its head
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. In electrical circuits, this law is used to calculate the relationship between voltage, current, and resistance. It helps in understanding how these factors interact and affect the overall behavior of the circuit.
False
In electrical conductors, electrons can move freely, allowing for the transfer of electrical energy. This results in conductors having high electrical conductivity. In contrast, in insulators, electrons are tightly bound to their atoms and cannot move easily, leading to low electrical conductivity. Insulators have high resistance to the flow of electricity due to this lack of electron mobility.
rod.
yes they were beaten
Using an analogy is the best way to explain this. Think of electrical current as cars on a road. The cars all want to get to their destination (which in a complete circuit is just to go in a loop) in the shortest time possible. As the road get's shorter the time it takes for the car to reach it's destination decreases.
