What else can I help you with?
What conditions are necessary for a current to be present in a circuit?
some resistance and potential difference
What happens to current in a parallel circuit?
in a parallel circuit, current get divided among the parallel branches in a manner so that the product of current and the resistance of each branch becomes same. The sum of the current in each branch is equal to the total current of the circuit.
How do you calculate amps in an electrical circuit?
To calculate amps in an electrical circuit, you use Ohm's Law, which states that Amps (I) Volts (V) / Resistance (R). This formula helps you determine the current flowing through the circuit based on the voltage and resistance present.
How to calculate amps in a circuit?
To calculate amps in a circuit, use the formula: Amps Volts / Ohms. This formula helps determine the current flowing through a circuit based on the voltage and resistance present.
What condition are necessary for a current to be present in a circuit?
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
How does resistance affect the current in a circuit?
Resistors are used for many things in an electronic circuit, including creating a voltage drop at some point; attenuating noise on a signal before it reaches the output stage; in combination with transistor devices, split a signal into 2 opposite phases; present a minimum load to a device to keep it working at its optimum point; to create an appropriate bias level for transistor device inputs; to control a timing circuit in conjunction with a capacitor; to create a tuned circuit in conjunction with an inductor, and/or a capacitor . . . . and the list goes on . . .
What would happen if they was no resistance?
current would go to a maximum, (if there was voltage present), if there was no voltage, no current would flow. the only thing that would limit the current flow (if voltage is present) is the small resistance of the cables, but say there was no resistance it would be like in a short circuit maximum current would flow at the instant voltage is applied. that is why RCD's work as they should, you want the most amount of current to flow at once because otherwise if the current was limited it would not trip in time to stop someone getting electrocuted.
What is the formula for finding ohms?
The formula for calculating resistance in ohms (Ω) is given by Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). Mathematically, this is expressed as R = V/I, where R is resistance in ohms, V is voltage in volts, and I is current in amperes. This relationship helps to determine how much resistance is present in an electrical circuit.
What is the phase shift between voltage and current when an capacitance is connected to the circuit?
The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only capacitance.
In a series circuit is resistance constant?
current
Why is voltage split over a series circuit?
Voltage drop due to the resistance present in the series circuit causes voltage split over a series circuit.
How many volts are there in 63 amps?
Without knowing the resistance present or the power being consumed, it is not possible to determine how volts are present in a circuit with 63 amps. Ohm's Law: Voltage = Current times Resistance Volt: Joules per CoulombAmpere: Coulombs per SecondWatt: Joules per Second
