What else can I help you with?
In which circuit is the voltage the same across all branches?
Parallel circuit.
How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
What voltage is measured across an open fuse or switch?
The full circuit voltage
Why is the voltage across a battery in a parallel circuit equal to the voltage across each bulb?
The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb. Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.
What is the voltage across any short circuit?
zero.........
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
What is the potential voltage across the circuit components in a series circuit?
In a series circuit, the potential voltage across the circuit components adds up to the total voltage of the circuit.
What is the formula for instantaneous current?
The formula for instantaneous current (i) in a circuit is given by Ohm's law: i = V / R, where V is the voltage across the circuit and R is the resistance.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
What is the voltage of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
Using ohm's law what is the formula to find the resistance in a circuit?
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
The voltage across a short circuit is equal to?
zero? the supply voltage? the supply voltage minus the individual coltage drops? the sum of the individual voltage drops? which one?
What is the voltage drop of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
In a circuit the voltage is the same across all branches?
In a series circuit, the voltage is the same across all components connected in the circuit. This is due to the conservation of energy principle, where the total voltage provided by the power source is equal to the sum of the voltage drops across each component.
In which circuit is the voltage the same across all branches?
Parallel circuit.
