Battery and Resistor

The Circuit

---

This circuit demonstrates a 5v battery connected in series with a 1kΩ resistor.

Simulation

---

• A transient simulation is run for 1 second.
• The voltage vbat+ is measured between the battery and the resistor R1.
• The current Ir is measured through resistor R1.

Notes

---

Use Ohm's law to calculate the current Ir through R1 as a function of battery voltage or R1 resistance.

$V = IR$     or     $I = \frac{V}{R}$     or     $R = \frac{V}{I}$

For    $V=5V$     and      $R=1k$

$I = \frac{5V}{1kΩ} = .005A = 5 mA$
