If we connect them in parallel, R eq = 30 Ω Therefore, in order to obtain a 150 Ω resistance, we have to connect the resistors in parallel and in series… Connecting two in parallel: R eq1 = 50 Ω How do we solve a problem with more than one emf and several loops? We can’t do it just by series and parallel resistor combinations. perpetualdalta. e.
