As the question didn't say whether the resistors were in series of parallel, perhaps both eventualities should be looked at. In series, the total resistance is the sum of the series resistors. The 30-ohm and 60-ohm resistors sum to 90 ohms. Total current will be voltage divided by resistance. The 220 volts applied divided by the 90 ohms will give 2.44 amps (2 4/9ths amps). In parallel, each resistor is connected indendently across the 220-volt source. Each one will "feel" the 220 volts and draw current accordingly. Since current equals voltage divided by resistance (just like always), we have to make the calculation for each resistor. The 220 divided by 30 equals 7.33 amps (7 1/3 amps). The 220 divided by 60 equals 3.66 amps (3 2/3 amps). The two branch currents each represent a part of the total circuit current, we have to find the sum of the branch currents to find the total current. Our 7.33 plus 3.66 amps sums to 11 amps.

What is the current when a voltage of 36 volts is applied to a circuit with a resistance of 6 ohms?
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
How are voltage resistance and current related?
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
What factors determine the voltage induced in a wire?
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
What happens to the applied voltage when a change in circuit resistance occurs?
When a dc supply is connected to a resistor, current flows. The current in amps is equal to the supply voltage divided by the resistance in ohms. The power used is the voltage times the current, and that appears as heat in the resistor, which might become hot to touch.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
How does current vary with the resistance in the circuit if the voltage is constant?
Inversely. As resistance increases, current dereases; given that the applied voltage is constant.
If the voltage applied to a circuit remains constant and the resistance in the circuit is increased the current will?
V = IR Where, V = voltage I = current R = resistance Thus if resistance is increased with constant voltage current will decrease
How any volts are produced in a circuit with 40 amp's of current flowing through a wire with 5 ohms of resistance?
It is a voltage (potential) applied to a load that causes a current to flow through the load. Ohm's Law encapsulates this principal and states Volts = Current x Resistance. In your example, the applied voltage would be 200 volts.
What is the current when a voltage of 36 volts is applied to a circuit with a resistance of 6 ohms?
Six amperes. Use Ohm's law: the current is the voltage divided by the resistance
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Does copper need a voltage to produce a current?
Copper can not of itself produce a current. <><><><><> However, resistance, be it copper or some other material, will produce a current if a voltage is applied to it. The rule is Ohm's law: Current = Voltage divided by resistance.
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
