Question
Four silicon diodes and a 10 Ω resistor are connected as shown in the figure below. Each diode has a resistance of 1 Ω. Find the current flows through the 10 Ω resistor.
Solution
Current flow through D1 and D3 = 2 Ω
Current flow through D2 and D4 = 2 Ω
These two are in parallel so
Net resistants = `1/2 + 1/2` = 1 Ω
Total Resistance = 1 Ω + 18 Ω = 19 Ω
V = 2.5 Ω
I = `"V"/"R" = 2.5/19`
I = 0.13 A
