Apply the values listed below to the circuit of Figure F–1 to determine the unknown quantity.
(a) I = 2 mA, R = 4 kΩ, V = __________?
(b) I = 6 μA, R = 200 kΩ, V = __________?
(c) I = 24 μA, V = 12 V, R = __________?
(d) I = 100 mA, V = 5 V, R = __________?
(e) V = 5 V, R = 50 kΩ, I = __________?
(f) V = 12 V, R = 600 Ω, I = __________?
(a) V = I × R = 2 mA × 4 kΩ = (2 × 10⁻³ A) × (4 × 10³ Ω) = 8 V
(b) V = I × R = 6 μA = 200 kΩ = (6 × 10⁻⁶ A) × (200 × 10³ Ω) = 1.2 V
(c) R={\frac{V}{I}}={\frac{12\,\mathrm{V}}{24\,\mu\mathrm{A}}}={\frac{12\,\mathrm{V}}{24\times10^{-6}\,\mathrm{A}}}=500\,\mathrm{k \Omega\,(or\,0.5\,M \Omega)}
(d) R={\frac{V}{I}}={\frac{5\,\mathrm{V}}{100\,\mathrm{mA}}}=50\,\Omega
(e) I={\frac{V}{R}}={\frac{5\,\mathrm{V}}{50\,\mathrm{k \Omega}}}=\,100\,\mu\,\mathrm{A}
(f) I={\frac{V}{R}}={\frac{12\,\mathrm{V}}{600\,\Omega}}=20\,\mathrm{mA}
