What is the current through each of the 15 ohm resistors?
The current through the 15 Ω resistor is 0.54 A.
What is the equivalent resistance of 10 ohms 30 ohms and 15 ohms resistors are connected in parallel?
Detailed Solution
The Correct answer is 5 ohm. For resistances that are connected in parallel, the formula is, Reciprocal of the equivalent resistance = Sum of reciprocal of all the resistances.
What is the formula when three resistance are connected in parallel?
If two resistors of equal resistance R are connected in parallel combination then the equivalent resistance of the combination is R / 2. Similarly, if three resistors of equal resistance R are connected in parallel combination then the equivalent resistance of the combination is R / 3.
What will be the voltage across 15 ohm resistance?
The voltage drop across a 15 Ω resistor in the circuit is 30 V having the polarity indicated.
What is the value of 2 ohm resistance Current?
Answer: The current through 2 ohm resistor is 2.1 A. Hence, the current through 2 ohm resistor is 2.1 A.
What is the resistance formula?
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
What is the resistance of an open switch?
An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference.
What is the unit of resistance?
The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated Ω), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm's law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I.
When the resistors are connected in parallel circuit then?
When resistors are connected in parallel, more current flows from the source than would flow for any of them individually, so the total resistance is lower. Three resistors R1=1.00Ω, R2=2.00Ω, and R3=2.00Ω, are connected in parallel.
What is resistor in parallel?
Resistors are in parallel if their terminals are connected to the same two nodes. The equivalent overall resistance is smaller than the smallest parallel resistor.
What is parallel connection of voltage?
Components connected in parallel are connected along multiple paths, and each component has the same voltage across it, equal to the voltage across the network. ... In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component.
What is voltage in parallel circuit?
Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. ... If one of the parallel paths is broken, current will continue to flow in all the other paths.
How do you find voltage in parallel?
Total voltage of a parallel circuit has the same value as the voltage across each branch. This relationship can be expressed as: ET = E1 = E2 = E3… In the above circuit, the voltage in each branch is 120 V.
