What do we call the materials which electricity can flow through easily

A set of lights consists of 20 identical lamps connected in series to a 240 V mains supply.What is the potential difference across each lamp?

Which of the following is not TRUE for electrons

Six wet cells made up of lead and lead dioxide plates in a sulfuric acid solution.

What ultimately happens to the cow in this situation? During a thunderstorm, if lightning hits the ground near a cow, then the current starts to spread out in the groud. Since the ground is wet, it is easier to spread horizontally, and also, the ground is somewhat positively charged. When the current starts to spread while a cow is eating grass, the current flows from the cow's mouth (A), goes through its leg (B) and goes back to the ground. The current will flow until the voltage becomes zero. Because cow's hind leg (D) has lower potential energy than its front leg (C), the current can flow through the cow.
The cow becomes a part of the electric circuit.

Which of these is the equation for Ohm's Law?

An oscilloscope is a device that is used to generate different waveforms.

Electric current loses energy as it moves through the filament because the filament ____ the flow of ____.

A wire of uniform cross-sectional area has a resistance R. The wire is stretched until its length increases by 10%. By assuming that the new wire has the same volume as before, the resistance of the new wire is

A closed path that electric current follows is?

Current flows as long as there is a closed path that connects one battery terminal to the other battery terminal.

As the current through a filament light bulb, its resistance increases. The best reason for this is:-

When an electric current flows through a wire what is moving?

What is the unit for energy?

What do the stripes indicate?

An electrical device that will only let the electric current flow in one direction is called

What if a bird sat on a power line that was very close to the ground, placing one foot on the wire and one foot on the ground?
