(R value specified in resistors in the circuit is ohm expression) NOT : I found the value of the current Id and it was 16 m A , but it was not there in the options, so I want to know what the correct answer is, although the options contain the voltage and required in the current question. Is there an error, and if the error is present, I want to answer the question to know what is required. pleasearrow_forwardFor the circuit shown in Figure P2.37, finda.
