Rearrange voltage, current and resistance, calculate power and explore ideal series and parallel DC circuits.
Useful to know
Can this answer every science question?
No. Each model has stated limits. Use structured fields when a prose question is unsupported. It does not predict reaction products or provide experiment procedures.
Are these official curriculum mappings?
No. These are concept-based resources. KICD and legacy KCSE mappings remain under review; no endorsement is claimed.
Where are my inputs stored?
Questions and scores remain in this tab only and are cleared by reset or reload. Copy and print are optional actions you control.

Science learning notes
Connect voltage, current and resistance
For an ideal ohmic resistor at fixed temperature, V=IR. Rearrange to I=V/R or R=V/I. Power transferred to the resistor is P=VI. In a simple series circuit the same current passes through both resistors; parallel branches share voltage.
Example: 12 V across 6 Ω gives 2 A and 24 W.
Common mistake: Milliampere and ampere differ by a factor of 1000. An open switch breaks the conducting path.
Can I use this to wire real electrical equipment?
This is an ideal virtual learning model. It does not select safe real components or provide household electrical instructions.
