V = IR R = V I V I Here, V = 220 V, I = 5A ∴ Four resistors (in parallel) are required to carry 5A on a 220 V line. ← Prev Question Next Question → Find MCQs & Mock Test JEE Main 2024 Test Series NEET Test Series Class 12 Chapterwise MCQ Test Class 11 Chapterwise Practice … WebOhm's law calculation formula. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): I =. V R. Example. I =. 20V 10Ω. = 2A. The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
How many 176 ohm resistor (in parallel) are required to carry 5 …
WebFeb 20, 2024 · Explanation: a) By ohms law V= RI. R= V/I = 2/0.1 = 20 ohm In second case also R= 4/0.2 = 20ohm b) Resistors in parallel are sum reciprocals of all Resistors which is equal to the total resistance reciprocal. Let the resistors be x 1/R = 1/R1 + 1/R2 ............. 1/R = X/176 R= 176/x By ohms law V= RI. 220= 176/X *5 X = 4 WebJun 24, 2024 · Best answer Let the total number of resistors be x. Given that: Current I = 5 A and Potential Difference V = 220 V According to Ohm’s law, V = IR Now for x number of resistors of resistance 176 Ω, the equivalent resistance of … 5g三大特性英文

WebMar 28, 2024 · Expert Answer let us assume there is n number of resistor required. since all the resistors are connected in parallel connection so the equivalence resistance = R = … WebMore information from the unit converter. How many milliohm in 1 ohm? The answer is 1000. We assume you are converting between milliohm and ohm.You can view more details on each measurement unit: milliohm or ohm The SI derived unit for electric resistance is the ohm. 1 milliohm is equal to 0.001 ohm. Note that rounding errors may occur, so always … WebAns. R1 = 2 ohm R2 = 3 ohm R3 = 6 ohm (a) When R2 and R3 are connected in parallel with R1 in series we get 1/R = 1/R2 + 1/R3 g= 1/3 + 1/6 = 1/2 Thus, R = 2 ohm Resistance in series = R + R1 = 2 + 2 = 4 ohm (b) When R1,R2, R3 are connected in parallel we get 1/R = 1/R1 + 1/R2 + 1/R3 = 1/2 + 1/3 + 1/6 = 1 ohm.
