Ang batas ni Ohm Ohm’s law — voltage pushes, resistance holds back, current flows

Malalim na aralinDeep dive 11 · ages 7 → high school

Tagalog: draft — for Kate / Janet to check.  Steps 1–2 for younger kids, 3 for ages 11+, 4–5 for high school.

1. Tubo ng tubig The water pipe

Presyon = boltahe, makitid na tubo = resistance, daloy = kuryente. Pressure is voltage, a narrow pipe is resistance, the flow is current.

2. Mga numero The numbers

I = V ÷ R. 6 V ÷ 3 Ω = 2 A. More voltage, more current. More resistance, less current.

3. Ang tatsulok The triangle

V sa itaas, I × R sa ibaba. Takpan ang hinahanap. V on top, I × R below. Cover the one you want: V = I × R, I = V ÷ R, R = V ÷ I.

4. Lakas at init Power and heat

P = V × I. LED resistor: R = (supply − LED volts) ÷ current. Pick the next standard value up and check the resistor's power rating.

5. Serye at parallel Series and parallel

Serye: R1 + R2. Parallel: (R1 × R2) ÷ (R1 + R2). Series adds up; parallel is smaller than either.

6. Calculator

Ilagay ang dalawang alam mo. Online only: type any two of V, I, R and it finds the third, plus the power.
