WebApr 29, 2024 · Q 10: How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line? From Ohm’s law, ∴four resistors of 176 Ω are required to draw the given amount of current. When three equal resistance are connected in parallel the effective resistance is 1 by 3 home if all are connected in series the effective resistance is? WebSolution Verified by Toppr Step 1 : Equivalent resistance Let n be the number of resistors to be connected in parallel Then, R 1=R 2=......=R n=R=176 Ω Now, R eq1 = R 11+ R 21 +..... R n1 ⇒ R eq1 = R 1n= 176n ⇒R eq=176/n ....(1) Step 2 : Applying Ohm’s law V=IR eq ⇒220=5R eq ⇒220=5×176/n ( Using Equation (1)) ⇒n=4

WebApr 8, 2024 · Hint: The equation for the net resistance for two resistors of resistances connected in parallel hast to be used first. Further, Ohm's law and Kirchoff’s current law will also be used to find the number of resistors. Formula used: The net resistance for two resistors of three resistances \[({R_1}),({R_2})\]and \[\left( {{R_3}} \right)\] connected in … WebNow, as per Ohm’s Law, we get, V I = 176 x V I = 176 x ⇒ x = 176×5 220 = 4 x = 176 × 5 220 = 4 Hence, in order to draw the required amount of current, four 176 Ω resistors will be … WebQ 10: How many 176 Ω resistors (in parallel) are required to carry 5 A on a 220 V line? Ans: For x number of resistors of resistance 176 Ω, Here Supply voltage, V = 220 V Current, I = 5 A Equivalent resistance of the combination = R, given as From Ohm’s law, ∴four resistors of 176 Ω are required to draw the given amount of current.
