3.0 or three
AnswerIt depends how they are connected.
In series, ther total resistance will be 220 ohms and, so, the current will be 120/220 = 0.545 A.
In parallel, ther total resistance will be 20 ohms and, so, the current will be 120/20 = 6 A.
Since it is a series circuit, the current is the same in all parts of the circuit. Just calculate the equivalent resistance, and use Ohm's Law.
It would be about 4 amps.
6
3 amps
1amp
4 amps
If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.
Two resistors wired in series (no mater if they have the same resistor value or not) will always have the same amount of current flowing through them. Therefore, the current flowing through the second resistor will be equal to the current flowing through the first one. The current through every component in a series circuit is the same. The voltage across every component in a parallel circuit is the same.
Opening any circuit will stop the current from flowing.
A resistor lets electricity flow, but in a calculated restriction of amount. An insulator prevents electricity from flowing across it - period.
Charge is potential, current is flowing.
The current would be about 20 volts.
the current flowing in will be low
half of the current flowing thru resistor 1.... V=IR.
as the given cells have the same current flowing in through them (current flowing through the cells connected in series is equal to the current flowing when connected in parallel ) equate the formula's of cells connected in series and cells connected in parallel.thus by equating we get the value of the internal resistor as 2 ohms.
If a 9V supply is connected to a 100-ohm resistor, then the current is not 2 Amps,or even close to it.I = E/R = 9/100 = 0.09 amp.
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance
resistor is a passive component which opposes the current flowing through a closed ckt. use in opposition of current in ckt .
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
ohm meter puts current thru a resistor to measure voltage drop E / I = R if the circuit already has current flowing the numbers are meaningless
V = 6 V R = 10 Ohm I = V/R = 0.6 A
