What else can I help you with?
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
What happens if you shorten the resistance wire in a circuit?
It shortens
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
In parallel circuit-what happens to the total resistance if one branch opens-Provide an example?
Increases
What happens to electrical in a resistor?
when you think of electricity and resistance think of it as water in a river and rocks in a river. The water being the electricity and the rocks being the resistance. when water in a river flows and then come across rocks that block the water from flowing constantly, it slows down the water. therefore when electricity is flowing through a circuit with resistance, when it hits the resistors it slows the flow of electricity.
What happens to electrical resistance of most conductors when heated?
Resistance goes up creating more heat which eventually leads to an open circuit.
What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
Why is heat observed when current flows through the circuit?
The heat observed in a circuit is the result of electrical resistance.Under normal circumstances, every electrical circuit has a certain amount of resistance to the flow of electricity. Electronflow opposed by the physical nature of the conductor. This is the fundamental nature of electrical resistance. Whenever this happens, the energy of those electrons is absorbed by the conductor (as opposed to flowing through) which then emitts this captured energy as heat. The higher a conductor's resistance, the more electrical energy is converted to heat by it.
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
When a dead short occur what happens to circuit resistance?
The circuit resistance is likely to gradually drop and in such case it will cause the circuit to burn down.
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
What happens if you shorten the resistance wire in a circuit?
It shortens
What happens the power consumption of a circuit as its resistance increases?
😉
What happens to the current when the circuit gets cold?
When a circuit gets cold, the electrical resistance of the components may increase. This increased resistance can lead to a decrease in current flow through the circuit as Ohm's Law states that current is inversely proportional to resistance. Additionally, some materials, like semiconductors, may exhibit changes in conductivity with temperature, affecting current flow as well.
What happens to amps when you increase the resistance of a circuit?
When you increase the resistance in a circuit, the current (amps) in the circuit will decrease. This is because Ohm's Law states that current is inversely proportional to resistance, so as resistance increases, current decreases.
What happens if a thermistor is heated?
the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.

How does a short circuit happen and what are its potential consequences?
A short circuit happens when an electrical current takes an unintended path due to a direct connection between two points in a circuit with low resistance. This can lead to overheating, sparks, fires, and damage to electrical components. The potential consequences of a short circuit include electrical fires, damage to equipment, and even electrical shocks. It is important to address short circuits promptly to prevent accidents and ensure safety.
