There is no such thing as 'resistance across' a load! The correct term is 'resistance of a load'.
To answer your question, it depends on how the loads are connected. If they are connected in series, for example, the total resistance is equal to the sum of the individual resistances. If they are connected in parallel, then you must use the following equation: 1/R = 1/R1 + 1/R2 + 1/R3 + etc.
For any other connection, you will have to work it out individually.
when A resistance is connected across the supply voltage, total input vooltage will be drop in the resistance when the resistances are connected across the supply voltage, total input vooltage will be devidedacross the resistances. IF R value will be high ,drop also high. IF R value wll be low ,voltage drop will be less.
No, the total resistance increases.
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
If they're connected in series the total resistance is 2000 ohms. If they're connected in parallel the resistance is 500 ohms.
A simple circuit has three resistors connected in series. The resistors are 14 ohms 12 ohms and 9 ohms. What is the total resistance of the circuit?
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
On Circuit Resistance = Close to the total load Resistance. Off Circuit Resistance = Near Infinitive High Resistance.
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
r/4If the two resistors are in parallel the find total resistance using this formula (1/R1 + 1/R2) = 1/R total
Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current passing through them. In a parallel configuration, the total resistance decreases as more resistors are added, while in a series configuration, the total resistance increases.
Total resistance is 120 ohms. The 120VAC will be split evenly over this 120 ohm load, so every ohm of resistance gets a volt. So there will be a 40 volt drop across the 40 ohm resistor.
What is the relation ship between total fixed cost and output?
When resistors are connected in series, the total resistance is the sum of the individual resistances. When resistors are connected in parallel, the total resistance is less than the smallest individual resistance.
In an electrical circuit, the phase angle represents the time delay between the voltage and current waveforms. The impedance of a circuit is the total opposition to the flow of current. The relationship between phase angle and impedance is that the phase angle is determined by the ratio of the reactance to the resistance in the circuit, which affects the overall impedance.
A voltage divider is a circuit that uses resistors to divide the input voltage into smaller voltages across multiple components. This is achieved by connecting the resistors in series, creating a voltage drop across each resistor based on their resistance values. The output voltage across each component is determined by the ratio of its resistance to the total resistance in the circuit.
Parallel circuits have multiple pathways for current to flow, meaning that if one component fails, the others can continue to function. The voltage is the same across all components in a parallel circuit, but the current is divided between the branches based on their resistance. The total resistance in a parallel circuit is less than the resistance of the individual branches.
Resistance can be calculated using Ohm's Law, which states that resistance (R) is equal to the voltage (V) across a component divided by the current (I) flowing through it: ( R = \frac{V}{I} ). Additionally, in a circuit with multiple resistors, total resistance can be calculated using series and parallel formulas. For resistors in series, the total resistance is the sum of individual resistances, while for resistors in parallel, the total resistance can be found using the formula ( \frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + \ldots ).
