Many circuits have safety devices such as fuse. A fuse contains a substance that melts if it gets hot. if a short circuit happens, the heat causes the fuse to melt. The circuit is broken. because the current stops ,no damage is done.

What is the affect of a series circuit on current?

by adding the the resistances in series the total resistance of the circuit increses and thus the crunt flowing in the circuit decrese. Ans 2 . the current in series circuit of constant resistance will always be the same . It will not effect the current .


In a series circuit each device that is added to the circuit decreases the?

Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.

How does the loading effect of an ammeter in a low resistance circuit compare to the loading effect in a high resistance circuit?

The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.


There are two light bulbs in a circuit wired in parallel a third bulb is added what is the effect on tolal resistance of adding the third bulb?

Adding any additional element in parallel will reduce the combined resistance. Do some sample calculations to get a "feel" for this: Total resistance (R) is calculated as 1/R = 1/R1 + 1/R2 + 1/R3... In other words, take the reciprocal of the individual resistances, add them, and then take the reciprocal of the result.


In an automotive electrical series circuit what will be the effect of adding additional resistance?

Everything in the series circuit will run dimmer / slower / cooler.Since the available voltage is constant (13.6 volts from the battery), increasing the resistancein the circuit causes the current through each device to decrease.


What is the effect of the increasing the number of resistor in series?

A: In a series circuit the currant is the same for all components but the IR drop will change foe each. By adding Resistance the current will decrease accordingly


What effect does decreased resistance have on a circuit?

resistance is the opposition to the flow of an electric current, therefore the current will decrease as the resistance increases. Resistance also creates heat. This is how the light globes in a circuit light up.


What happens to the overall current of the circuit if the number of receivers?

If the number of receivers in a circuit increases, the overall current can be affected depending on how the receivers are arranged. In a parallel circuit, adding more receivers generally decreases the total resistance, which can increase the overall current if the voltage remains constant. In a series circuit, adding more receivers increases the total resistance, leading to a decrease in overall current. Therefore, the effect on current depends on whether the receivers are connected in series or parallel.
