The current is 1.4 amps, as already stated. The voltage is 45 x 1.4 volts.
Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
To determine the value of Stabilizing resistor Rs = Vs/Is = If(Rct +2Rl)/Is Where, Rs = resistance value of the stabilizing resistor Vs = voltage at which the relay will operate Is = current flowing through the stabilizing resitor and the relay If = maximum secondary fault current magnitude Rct = internal resistance of the current transformer Rl = resistance of attached wire leads
The current depends on the total effecvtive resistance of everything connectedacross the battery.If the resistor is the only component there, then the current is E/R = 12/3 = 4 amperes.
Current flow. It's also worthy of noting that a resistor doesn't limit-by, it limits-to, and the current is dependent on the voltage. I[A] = U[V] / R[ohm] It's also worth to note, that the power flowing through said resistor with resistance R is I[A] * U[V] for DC circuits - helps to remember this well when picking appropriately-rated resistors for replacement. Example: let's say we have a 20-ohm, 2W resistor. If we place it in a circuit with 5V, we will get 5V / 20ohm = 250mA (0.25A) of current flowing through the resistor. The power the resistor will "see" is 250mA * 5V = 1.25W, so it's safe. But let's now put that same resistor in a 12V circuit. The current flowing will be 12V / 20ohm = 600mA (0.6A), and the power will be 600mA * 12V = 7.2W, so the resistor will burn.
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.
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 .
by resistor installation
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.

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
You'll see a voltage drop across a resistor if current is flowing through it. It only has to be a part of a complete circuit, i.e. one in which current is flowing.
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.
POWER=VI. V=voltage I= current
The value of a resistor with 5 volts across it and 20 milliamperes of current flowing through it is 250 ohms. Ohm's Law: E = I R R = E/I
