In the case of an a.c. circuit, capacitors oppose current because of their capactive reactance, expressed in ohms. Capacitive reactance is inversely-proportional to the capacitance of the capactor and to the frequency of the supply. So, adding a capacitor is series with an existing load will reduce the load current. On the other hand, adding a capacitor in parallel with an existing load will decrease the load current.

If the resistance in the circuit is increased what will happen to the current and voltage?

* resistance increases voltage. Adding more resistance to a circuit will alter the circuit pathway(s) and that change will force a change in voltage, current or both. Adding resistance will affect circuit voltage and current differently depending on whether that resistance is added in series or parallel. (In the question asked, it was not specified.) For a series circuit with one or more resistors, adding resistance in series will reduce total current and will reduce the voltage drop across each existing resistor. (Less current through a resistor means less voltage drop across it.) Total voltage in the circuit will remain the same. (The rule being that the total applied voltage is said to be dropped or felt across the circuit as a whole.) And the sum of the voltage drops in a series circuit is equal to the applied voltage, of course. If resistance is added in parallel to a circuit with one existing circuit resistor, total current in the circuit will increase, and the voltage across the added resistor will be the same as it for the one existing resistor and will be equal to the applied voltage. (The rule being that if only one resistor is in a circuit, hooking another resistor in parallel will have no effect on the voltage drop across or current flow through that single original resistor.) Hooking another resistor across one resistor in a series circuit that has two or more existing resistors will result in an increase in total current in the circuit, an increase in the voltage drop across the other resistors in the circuit, and a decrease in the voltage drop across the resistor across which the newly added resistor has been connected. The newly added resistor will, of course, have the same voltage drop as the resistor across which it is connected.


What happens to the voltage in a series circuit when more loads are added?

A: assuming a infinite current source the current will increase accordingly


In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?

By adding more light bulbs


Why is there less current in a circuit with four bulbs than there is in a circuit with one bulb?

yes because of bulb resistance :)


What happens if you add more batteries to a circuit?

Depends on how you add them. Added in series, the voltage will increase, maybe to the point of damaging the LED. If the LED survives, it will shine brighter. Added in parallell, the LED will shine the same, and will be able to shine longer before draining the batteries.

What happens when one bulb is added to a series circuit?

The resistance is increased, the voltage across each bulb is decreased and the current through the circuit is reduced.


How does added resistance affect the brightness of the bulb?

Added resistance in a circuit will decrease the current flowing through the circuit, resulting in a decrease in the brightness of the bulb. This is because the bulb's brightness is directly proportional to the current passing through it. More resistance means less current, which leads to reduced brightness.


What would happen if more capacitors were added to a series circuit already containing two capacitors?

A: For one thing the total capacitance will decrease . If the voltage rating are different then more problem will become evident. That is if they are added in series.


If you have a DC passing through a circuit will the current decrease when you add a DC motor and if so by how much?

In the circuit where the DC motor is added, it was not specified whether the motor was added in series or in parallel to circuit elements. If it was added in series, it will increase circuit resistance and it will cause circuit current to go down. In parallel, the motor will reduce total circuit resistance, and circuit current will increase.


What is added to a circuit to make the current smaller?

The reduction of voltage or the increase of resistance will reduce the current in a circuit.


What happens to the current in a parallel circuit when more bulbs are added?

When more bulbs are added to a parallel circuit, the total current in the circuit increases because each bulb provides an additional path for current to flow. This is because in a parallel circuit, the current is divided amongst the branches, so adding more branches (bulbs) will increase the total current.


What is the second component of a circuit?

The second component of a circuit typically refers to the second element added to the basic circuit configuration after the power source, such as a battery. Common examples include resistors, capacitors, or inductors, which serve various functions like limiting current, storing energy, or filtering signals. The specific component depends on the circuit's purpose and design, as each element contributes to the overall functionality of the circuit.


What would be different about the circuit if a resistor were added in series with the light bulbs?

The total current in the circuit will decrease.


What happens to the total current provided by the battery as more bulbs are added to a parallel circuit?

The total current provided by the battery increases as more bulbs are added to a parallel circuit. This is because each branch in a parallel circuit receives the full voltage of the battery, leading to more current flowing through each branch as more loads (bulbs) are added.


What 2 voltages is a short circuit made of?

Circuits are not made of voltages, they are made of loops. A short circuit exists when a connection is added that is not supposed to be part of the intended circuit as designed. This added connection produces extra loops in the circuit that typically prevent current from reaching parts of the circuit where it is needed and can cause excessive current to flow in other parts of the circuit, resulting in damage to the components in the circuit.


What happens to the current measured as more bulbs added?

It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.


What can be used to reduce to current in a circuit?

A: Any resistance added in series will reduce the current unfortunately will also reduce the voltage
