## What are the 3 rules for parallel circuits?

From this definition, three rules of parallel circuits follow:

- All components share the same voltage.
- Resistances diminish to equal a smaller, total resistance.
- Branch currents add to equal a larger, total current.

## What is the rule for voltage in a series circuit?

Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.

## What is the relationship between voltage and current in a capacitor?

To put this relationship between voltage and current in a capacitor in calculus terms, the current through a capacitor is the derivative of the voltage across the capacitor with respect to time. Or, stated in simpler terms, a capacitor’s current is directly proportional to how quickly the voltage across it is changing.

## What is relation between current and resistance?

The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant.

## Is higher or lower amps better?

A higher voltage system is more efficient than a lower voltage since it experiences less energy loss from resistance given the same amount of power draw. You get the same exact voltage—but with 80 amps of current. That’s 80% more energy!

## What is low current and high current?

The voltage in the wire (or power plant) is high and the resistances of the wires are low, so you think that the current should be high. This is what makes the current in this circuit low. So you have high voltage and low current because of high resistance of the receiver between the wires.

## What is the difference of voltage and current?

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing.

## What causes low current in the house?

Age and corrosion are a common cause of low voltage, as is dirty connections and poor insulation. Poor or damaged splicing work can also be a cause. In some cases, the wires used to carry electricity have a lower gauge than is necessary. Low voltage problems could be the result until the wires are replaced.
