The resistor \( R_1 = 30 \, \Omega \) and \( R_2 = 10 \, \Omega \) are connected in parallel to a 20 V battery. Find the heat developed in the resistor \( R_1 \) in one minute
Show Hint
For components connected in parallel, the voltage across them is the same. This makes the power formula \( P = V^2/R \) and heat formula \( H = (V^2/R)t \) particularly useful.
