What else can I help you with?
What is the total resistance of a parallel circuit with branch voltages of 440 volt and 440 volt and branch currents of 4 amp and 16 amp?
resistance = volt / current . 440 volt across a parallel circuit means the same 440 volt across both resistance s. hence resistance r = volt / current . 440 / 20 amp = 27.5 ohms total resistance
If Three 12 volt batteries are connected in parallel what is the effect on the circuit?
There will be no effect on the voltage. That is the effective voltage will be only 12 volt. But there will be increase of current.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
What is the same in a parallel circuit?
Always voltage constant in parallel circuit if you look your house wiring all are in parallel therefore 220 volt present in every house but current is different
What is the current in a 12 volt circuit with two 6 ohm resistors connected in parallel?
1 amp. formula E=IR
Three 15 ohm resistors are connected in parallel to a 30 volt battery What is the current through each branch of the circuit?
2 amps
What is the current in a 12-volt circuit with two 6-ohm resistor connected in parallel?
Two 6-ohm resistors in parallel have a net effective resistance of 3 ohms.With 3 ohms connected across a 12-volt supply, the current is 12/3 = 4 amperes.
How long does current remain in a 220 volt circuit?
The current in a 220 volt circuit depends on the resistance of the load connected to it. Ohm's Law (I = V/R) states that current (I) is equal to voltage (V) divided by resistance (R). So, the current will vary based on the resistance of the circuit.
If a 12 volt parallel circuit has 4 lamps and each lamp consumes 1 amp what is the resistance of each lamp?
Assuming you mean the 4 lamps are in parallel with each other: the total voltage drop across each lamp is still 12V. As we know that V= IR (Voltage = I Current times Resistance) 12 = 1 x R so Resistance = 12 Ohms for each lamp.
4 nine volt batteries are connected in parallel how much voltage is active across the circuit?
9 volts. They are in parallel, so the voltage remains the same. More current is available however.
How is current in a circuit checked?
by a volt meter / ameter
When you compare 3 lamps in a series circuit to the same 3 lamps in a parallel circuit connected to the same 12-volt battery which statement is TRUE?
If a lamp burns out in parallel circuit, the other two lamps will continue to glow. If a lamp burns out in the series circuit, the other two lamps will also go out. If 3 lamps are in one series circuit, and one of them goes out, the loop is disconnected.
