Plz I need help!! 18- Consider the circuit represented in
figure 16.
The dry cell maintains a constant
voltage Upx=9 V; Ri=100 12 and
R2200 2
a Find the resistance of the resistor
equivalent to the two resistors.
b- Calculate the current sent by the dry
cell
Calculate the voltages UI and Uz across
Ri and R2 respectively. Verify the law of
addition of voltages
