If resistors decrease current , then why value of I Remains unchanged means before undergoing value off I is i1 then after undergoing resistor same i1
The cathode of a photoelectric cell is changed such that the work function changes from W1 to W2 (W2>W1). If the current before and after change are l1 and l2 all other conditions remaining unchanged, then (assuming hn > W2)
Find the value of ∣∣∣2+i2−i1+i1−i∣∣∣ if i2=−1.
