Several150 Ω resistors are to be connected in such a way that a current of 2 A flows from a 50 V source. How many such resistors are required along with a mode to connect them?​

Answer»

resistorsExplanation:Given :Many 150 ohms resistor are connected 2 AMPERES of CURRENT should flow in them Source shall have voltage of 50 volts.To find :No of RESISTORS to be connected.Using ohms law:V=IR50=2×Rr = R = 25 ohmsNow we NEED to find number of 150 ohms resistor to be connected in parallel to get equivalent resistance equal to 25 ohms.If resistance is same in all resistors, req = R/no.of resistors.150/no.of resistors = 25No.of resistors = No.of resistors = 6Six 150 ohms resistors must be connected in parallel to get an equivalent resistance of 25 ohms.
