Use the formula P= VI (power = potential x current) where (watts = volts x amps).
The current I in amperes is equal to the watts divided by the volts, 40/120.
The bulb is using 1/3 amp of current.
To calculate the current in the AC circuit, we can use the formula P = V * I, where P is power (60 watts), V is voltage (120 volts), and I is current. Rearranging the formula to solve for current I, we get I = P / V. Plugging in the values, I = 60 watts / 120 volts = 0.5 amps. Therefore, the current flowing through the circuit is 0.5 amps.
Electrical current is equal throughout a series circuit.
A simple circuit containing a light switch in the on position is a closed circuit. In a closed circuit, electrical current can flow freely, allowing the light to illuminate. If the switch were in the off position, it would create an open circuit, interrupting the flow of electricity and turning the light off.
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
The continuous loop that an electric current flows through is called a circuit. It typically consists of a power source (such as a battery), conductive wires, and components like resistors, switches, and light bulbs. When the circuit is complete, electrons can flow continuously through the loop, allowing electrical energy to be transferred and used.
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
To calculate the current in the AC circuit, we can use the formula P = V * I, where P is power (60 watts), V is voltage (120 volts), and I is current. Rearranging the formula to solve for current I, we get I = P / V. Plugging in the values, I = 60 watts / 120 volts = 0.5 amps. Therefore, the current flowing through the circuit is 0.5 amps.
yes
the heated rear screen circuit has a higher resistance compared to the side light circuit
The circuit current is interrupted and all the lights will go out.
the same current flows through both light bulbs
Incomplete circuit
They don't unless you speaking about a parallel circuit in which total currect would be the sum of all the currents in each light bulb (The more light bulbs, the more current draw) If you're talking about a series circuit, nothing at all happens to the current, as in a seires circuit current is constant throughout the entire circuit (voltage changes). In a case such as this the more light bulbs in the circuit, the less the voltage becomes across those bulbs (furthest from the source), thus they will become dimmer due to lower power (P=IE).
No. Circuit is open but still HOT.
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
A light bulb would act as a load in a circuit. It transforms electrical energy into light energy and heat when current passes through it. It offers resistance to the flow of current, causing it to light up.
