In a common emitter transistor circuit the valtage drop across the collector is 1 V and curent gain is 70 if the collector resistor is 3 k `omega` calculate the base current

Explanation

To solve the problem step by step, we need to calculate the base current (IB) in a common emitter transistor circuit given the voltage drop across the collector (VCE), the current gain (β), and the collector resistor (RC).

### Step 1: Identify the Given Values
- Voltage drop across the collector (VCE) = 1 V
- Current gain (β) = 70
- Collector resistor (RC) = 3 kΩ = 3 × 10^3 Ω

### Step 2: Calculate the Collector Current (IC)
