# Puzzle On Current Of electricity

• Delzac
In summary, electricity flows through a circuit in a continuous loop from the power source, through the wires, and back to the power source. AC (alternating current) and DC (direct current) are two types of electric currents, with AC being used for power transmission and DC being used for electronic devices. The strength of an electric current is measured in amperes (A) using an ammeter. The flow of electricity in a circuit is affected by factors such as voltage, resistance, and wire material, as well as temperature and wire length. Ohm's law is a fundamental principle in electricity, stating that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance, and is commonly used to calculate

Hi all,

In a lighting storm,why do cows get killed more often than chickens?(i'm serious)

Any help will be appreciated.

I hope no-one answers this for you because it is really easy. Think of a spark-plug. What happens when it gets worn out?

Think about the spacing of their legs.

## 1. How does electricity flow through a circuit?

Electricity flows through a circuit in a continuous loop from the power source, through the wires, and back to the power source. This flow of electricity is known as an electric current.

## 2. What is the difference between AC and DC current?

AC (alternating current) and DC (direct current) are two types of electric currents. AC current changes direction periodically, while DC current flows in one direction. AC current is used for power transmission, while DC current is used for electronic devices.

## 3. How do you measure the strength of an electric current?

The strength of an electric current is measured in amperes (A). This can be measured using a device called an ammeter, which is connected in series with the circuit.

## 4. What factors affect the flow of electricity in a circuit?

The flow of electricity in a circuit is affected by several factors, including the voltage of the power source, the resistance of the wires, and the type of material the wires are made of. Other factors such as temperature and length of the wires can also impact the flow of electricity.

## 5. What is Ohm's law and how is it used in electricity?

Ohm's law states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance. This means that as the voltage increases, the current also increases, and as the resistance increases, the current decreases. Ohm's law is used to calculate the current, voltage, or resistance in a circuit using the formula I = V/R.
