The power will be the product of the square of the current and the resistance of the load. The fact that the circuit is a parallel circuit is irrelevant to this question.
P = I2R = 0.032 x 1000 =0.9 W

Is the power dissipated in a parallel circuit larger than the power dissipated in a serial circuit?
Consider t resistors with same Ohmic values. If they are in series total resistance Rt = R1 + R2. if they are in parallel then total resistance Rt = 1/R1 + 1/R2. Series connection will have higher resistance.
When a battery is connected across a high resistance in parallel with a low resistance more power is dissapited in the low resistance Is this statement true or false?
true
What is the difference between a simple circuit and a parallel circuit?
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
When you have watts in a series circuit do you add up the total or is it the reciprocal?
The power dissipated by the complete circuit, no matter whether it's a series or parallel one, is the simple sum of the power dissipated by each component of the circuit.
Would a multimeter connected in parallel as part of the circuit measure current or power consumption or voltage or wattage?
A typical multimeter measures voltage and resistance "in parallel" or current in-line with the circuit. It all depends on the model. 'Multi' means many different modes. Some have more than others. Some multimeters can measure current, but require you to alter the lead configuration and plug into different sockets. If you have the meter set for Current measurement and you put it in parallel instead of series, it will cause a dead short and could damage the meter. (They usually have a fuse inside for protection). Knowing any two of the three parameters you can calculate the third by Ohm's Law: Voltage = Current x Resistance. Knowing Current and Voltage you can calculate power as Volts x Amps = Watts for resistance loads.
What is the power of a parallel circuit with a resistance of 1000 ohms and a current of 0.03 amps?
.9 watts.
Is the power dissipated in a parallel circuit larger than the power dissipated in a serial circuit?
Consider t resistors with same Ohmic values. If they are in series total resistance Rt = R1 + R2. if they are in parallel then total resistance Rt = 1/R1 + 1/R2. Series connection will have higher resistance.
The amount of current that flows in a parallel circuit branch depends on the what?
... the voltage of the power supply and the resistance of that branch alone.
Which uses more energy parallel circuit or a series circuit?
That depends. For example, if the circuit is consisted of two resistors, 2 ohms each, the equivalent resistance (Req) of these two resistors in series is 4 ohms, and the Req of these two resistors in parallel is 1 ohm. If the same voltage is applied, say 4 V.power consumed in a resistance = V2/R.The parallel circuit: Power = 4 * 4 / 1 = 16 [W].The series circuit: Power = 4 * 4 / 4 = 4 [W].With everything else the same, a parallel circuit consumes more energy than a series circuit.Note that circuits of only simple resistors are discussed. You need to consider each circuit on its merit.================================AnswerIt depends. In both cases, the total energy expended will be the sum of the energies expended by each individual load.
What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
What kind of circuit is a power bar?
a parallel circuit
Why dont series circuits shine as bright as parallel circuits?
By connecting components in series, you are increasing the equivalent resistance (known as thevenin resistance) of the circuit. Power is equivalent to Voltage^2 / Resistance. Therefore, by increase the resistance, you are decreasing the amount of power provided by the source.
In a parallel circuit does the power of each branch add up?
Yes, the total power dissipated through the circuit is equal to the sum of the power of each branch in a parallel circuit.
How does the brightness of each bulb in a parallel circuit compare to the brightness of the bulb in a simple circuit?
The brightness of each bulb in a parallel circuit is the same as the brightness of a bulb in a simple circuit. By Kirchoff's voltage law, each element of a parallel circuit has the same voltage drop across it. With the same voltage, the same type of bulb will dissipate the same power, and have the same brightness.
What is a parallel circiut?
Something that contains a voltage circuit and wires.
What effect does reducing resistance have on the power in a circuit?
Since power = voltage2/resistance, reducing the resistance will increase the power of the circuit. Incidentally, power is not 'consumed'; it's energy that's consumed.
What is the power of a parallel circuit with a resistance of 1000 and a current of0.03 a?
I don't know what the parallel circuit has to do with it. You've onlygiven me a resistor and the current through it.When 0.03A of current passes through a 1,000Ω resistor, the resistordissipates energy at the rate of 0.9 watt.
