[填空题]
How many $\frac{1}{2}-W$ resistors, each of the same resistance, must be used to produce an equivalent $2.2-k\Omega$, $3.5-W$ resistor? $\Omega$ resistors, each rated at ½ W, in
What is the resistance of each, and how must they be connected? Do not exceed $P\,=\,\frac{1}{2}W$ in each resistor. k$\Omega$ resistors, each rated at ½ W, in
